Which of the following best completes the passage below?

Sales campaigns aimed at the faltering personal computer market have strongly emphasized ease of use, called user-friendliness. This emphasis is oddly premature and irrelevant in the eyes of most potential buyers, who are trying to address the logically prior issue of whether___.

(A) user-friendliness also implies that owners can service their own computers

(B) personal computers cost more the more user-friendly they are

(C) currently available models are user-friendly enough to suit them

(D) the people promoting personal computers use them in their own homes

(E) they have enough sensible uses for a personal computer to justify the expense of buying one

The key is E. Why? Where is the linkage?

Thanks

"Buying a computer is pretty expensive. Do I really need it?" The smart consumer is still trying to figure this out. So the ads on "user-friendliness" don't really matter much.
